Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection molds, and in particular to a wire harness injection mold. Background Technology
[0002] In modern industrial production, wire harnesses, as crucial components for electrical connections, are widely used in the automotive, electronics, and home appliance industries. The terminals of wire harnesses typically require injection molding to form protective connectors, ensuring the stability and reliability of the connection. Currently, existing wire harness injection molds have some shortcomings in use. On the one hand, the injection efficiency is low. After injection molding a wire harness, it is necessary to wait for the mold to open and remove the finished product before installing a new wire harness for the next injection. The waiting and replacement time in between is long, which affects the overall production progress. On the other hand, the limiting of the wire body is not stable enough. During the injection process, the wire body may shift, which will affect the injection quality of the connector and even lead to product scrap.
[0003] Therefore, it is necessary to invent a wire harness injection mold to solve the above problems. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] This utility model provides, for example Figure 1-7The wire harness injection mold shown includes an upper mold 1, a lower mold 2 and a wire harness 3, the wire harness 3 also includes a wire body 31 and a terminal 32; The upper mold 1 and the lower mold 2 have a first mold groove 4 and a second mold groove 5 respectively on opposite sides. A first injection mold 6 and a second injection mold 7 are respectively housed within the first mold groove 4 and the second mold groove 5. Corresponding semi-injection grooves 8 are formed on the rear sides of both the first injection mold 6 and the second injection mold 7. When the first injection mold 6 and the second injection mold 7 are combined, the semi-injection grooves 8 on the first injection mold 6 and the second injection mold 7 combine to form a complete injection groove. A first injection port 9 is formed at the top of the upper mold 1, and a flow divider groove corresponding to the first injection port 9 is formed inside the upper mold 1. Two... A second injection port 10 corresponding to the flow divider is provided. The semi-injection groove 8 on the first injection mold 6 is connected to the second injection port 10, the flow divider, and the first injection port 9. By inserting the terminal 32 of the wire harness 3 into the slot 15 on the assembly block 14, and making a part of the terminal 32 in the semi-injection groove 8 of the first injection mold 6 and the second injection mold 7, the upper mold 1 is connected to the cylinder. The cylinder pushes the upper mold 1 down, thereby merging the first injection mold 6 and the second injection mold 7. The injection solution is added to the semi-injection groove 8 through the first injection port 9 and the second injection port 10, and a connector can be injection molded on the outside of the terminal 32.
[0015] The upper mold 1 and the lower mold 2 are each provided with a first groove 11 on their opposite sides, and the first injection mold 6 and the second injection mold 7 are each provided with a second groove 12 on their opposite sides. The first groove 11 and the second groove 12 are connected to each other, and the second groove 12 is connected to the semi-injection groove 8. The line body 31 can be limited and clamped by the first groove 11 and the second groove 12.
[0016] The upper mold 1 and the lower mold 2 each have an assembly groove 13 on their opposite sides, and an assembly block 14 is provided in the assembly groove 13. The front side of the assembly block 14 has a slot 15 corresponding to the terminal 32. Through the separately provided assembly block 14, the wire harness 3 can be installed on another unused assembly block 14 during the injection molding process. After the injection molding is completed, the assembly block 14 with the injection-molded wire harness 3 is removed from the upper mold 1 and the lower mold 2, and the assembly block 14 with the un-injected wire harness 3 is installed in the assembly groove 13 of the upper mold 1 and the lower mold 2, thereby improving the injection molding efficiency of the wire harness 3 connector.
[0017] A rectangular frame 16 is provided on the outside of the slot 15. The rectangular frame 16 is fixedly connected to the side wall of the assembly block 14. Through the rectangular frame 16, a rectangular groove can be formed on the connector during the injection molding of the terminal 32 to ensure the sealing of the terminal 32 connection.
[0018] A plug rod 17 is fixedly connected inside the semi-injection groove 8. Through the plug rod 17, a mounting hole can be formed on the connector during the injection molding of the terminal 32.
[0019] The working principle of this utility model is as follows: First, the terminal 32 of the wire harness 3 is inserted into the slot 15 on the assembly block 14, so that a part of the terminal 32 is in the half-injection groove 8 of the first injection mold 6 and the second injection mold 7. At the same time, the wire 31 passes through the first wire groove 11 and the second wire groove 12 in sequence. The upper mold 1 is connected to the cylinder, and the cylinder is started. The cylinder pushes the upper mold 1 down, so that the first injection mold 6 and the second injection mold 7 are combined. At this time, the two half-injection grooves 8 are combined into a complete injection groove. Then, the injection solution is injected through the first injection port 9. After the injection solution is diverted by the diversion groove, it enters the half-injection groove 8 through the two second injection ports 10 to inject the outer side of the terminal 32 to form a joint. During the injection process, another wire harness 3 can be installed on the spare assembly block 14. When the current injection is completed, the cylinder drives the upper mold 1 to move up, remove the assembly block 14 with the injected wire harness 3, and install the spare assembly block 14 into the assembly groove 13 for the next injection, thereby improving the injection efficiency.
[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
